Hi EFI family,

Im having an issue removing post shift timing corrections on an auto 535xi.

The car runs well but each time I shift, it drops a ton of timing.

I've tried lowering timing, adding fuel, playing with boost control (PID), and tuning VANOS all with no real success. I feel like I'm missing something.

Fuel trims went positive at the end of the pull because the car is using port injection and a fuel scalar table adjustment is needed (this will be corrected for later). Stock turbos, downpipes, upgraded low pressure fuel pump, intercooler, and tune with TunerPro. Fuel is full e85

Hi Carl, ANY help will require YOUR .XDF (mask) files ?

I use Tuner Pro RT for the OBD-I USPS Memcals I manufacture.

Hi Lance,

How would you like me to upload the XDF?

Im using IJE0S from this.
https://github.com/dmacpro91/BMW-XDFs

I normally download all then unzip.

Hi Carl, definition files ARE the one you chose, noting YOUR "tech" STATES MANY, then chose AGAIN IJEOS.
This WORK, I understand your need for others to your work, is to provide the XDF.
This type of file is EASY to send, post, etc.
The easiest method is ALWAYS the best method with LESS ERROR.

I had no luck using the FTP site.
